The Field Trip is a free podcast that takes science out of the lab and into the world. We are currently on hiatus as we work on new book projects, but you can listen to older episodes for free on this site!

The Field Trip Podcast gets bubbly with fermentation

On our tastiest field trip yet, we investigate the delicious world of fermentation and the bacteria that make it possible. We take a trip through Cultured Pickle Shop in Berkeley, where owner Alex Hozven explains the art and science behind fermenting food and shows us how they make sauerkraut, pickles, kombucha and other mysterious surprises. At Cultured, they use traditional methods of fermentation — that means no heat, and no vinegar, but plenty of Lactobacilli and other friendly microbes. Come with us as we explore “the cave” and learn about its billions of tiny workers.

Then we check in with fermentation revivalist Sandor Katz, author of Wild Fermentation: The Flavor, Nutrition and Craft of Live-Culture Foods and expert on all things pickle-y. We hear about some surprising and tasty treats that we had no idea are made through fermentation, and learn about some of the ancient roots of pickling, and why it was such an important method of food preservation in the era before refrigeration.
